Advanced Crystal Beast Cobalt Eagle

If "Advanced Dark" is not in the Field Zone, send this card to the GY. You can send this card from your hand or field to the GY; add 1 "Advanced Dark" from your Deck to your hand. Once per turn: You can target 1 "Advanced Crystal Beast" card you control; either return it to the hand or place it on the top of the Deck. If this face-up card is destroyed in a Monster Zone, you can place it face-up in your Spell & Trap Zone as a Continuous Spell, instead of sending it to the GY.
